CHARLES 1?. HOWE, OF WALTERS, OKLAHOMA,

WORKING BARREL.

Application filed September 20, 1924. Serial No. 735,934.

To all whom, it may concern:

Be it known that I, CHARLES P. Hows, a

citizen of the United States, residin at Walters, in the county ofCotton and tate of Oklahoma, have invented certain new and usefulImprovements in Working Barrels, of which the following is aspecification.

This invention relates to working barrels especially adapted to be usedin oil wells, and it consists in the novel features hereinafterdescribed and claimed.

An object of the invention is to .provide a working barrel or pump ofsimple and durable arrangement aving its arts and features so assembledand associated that gas, oil, and other fluids may be readily pumped outof the well, without the use of tubing, other than the regular casing inthewell. I

In the accompanying drawing:

Figure 1 is a vertical sectional view of the working barrel.

Figure 2 is a transverse sectional view thereof, cut on the line 22 ofFigure 1.

As illustrated in the accompanying drawing the well casing is indicatedat The working barrel comprises a cylindrical fitting 2, provided at oneend with a n pple portion 3, and at its opposite end with a nippleportion 4. The nipple ortion 1 is of greater diameter than the nippleportion 3. Passageways 5 pass longitudinally through the fitting 2 andcommunicate at their lower ends with the interior of the nipple 4. Thesaid passages 5 are disposed exteriorly of the nipple 3, and a valvemember 6 is slidably mounted upon the nipple 3 and the same is adaptedto close over the upper ends of the passageways 5. The fitting 2 isfurther provided with longitudinally disposed openings 7, which arelocated cxteriorly of the nipple 4:. A valve member 8 is slidablymounted upon the nipple 1 and is adapted to close against the lower endsof the openings 7 A nut 9 is screwed upon the lower end of the nipple 4and is adapted to retain the valve members in position upon the nipple.The fitting 2 is provided at its outer side with a soft rub ber sleeve10, adapted to fit snugly against the interior surface of the wellcasing 1. A cage 11 is mounted upon the upper end of the fitting 2 andis provided with a number of openings 12. A cylinder 13 is connected atits upper end with the nipple 4, and carries at its lower end a ballvalve 14. A valve controlled plunger 15 is located in the cylinder 13,and is connected with the stem 16, which extends through the center ofthe fitting 2, through the nipple 3, and through the center of the cage11. A perforated liner 17 is located in the casing 1, at the lowerportion of the well.

When the pump is lowered into the well, the valve 8 rests upon the upperend of the liner 17, and closes the lower end of the openings 7 andwhich remains closed, duringthe operation of the pump. In operation, thestem 16 and plunger 15 are reciprocated in the cylinder 13 by gas, oil,and other fluid drawn into the c linder 13 and forced upwardly throughtile passageway 5 and under the valve member 6 of the cage 11.

From the cage 11, the fluid asses through the openings 12 and enters t eupper portion of the casing and flows out at the top of the well. Inorder to remove the pump from the well, the fitting 2 and valve 8 arelifted oil of the upper end of the liner, and thus the valve may pullaway from the lower ends of the openings 7, and permit the pumpto belifted out of the Well, without lifting the liquid in the well above thepump. In an oil well which does not have gas pressure enough to causethe oil to flow, the hereinbefore described device may be used, and atless expense than by swabbing the well, in order to remove the contentsfrom the upper portion thereof before lifting the pum out of the well.There are wells, in whic the production is too large to pump with theregular pumping equipment, and such wells do not have sufiicient gaspressure to cause the oil to flow, and for that reason the producer isforced to swab. When thepresent device is used, it will agitate thecontents of the well and keep the contents flowing, and when it isdesired to remove the pump from the well, in order to make repairs, 1tonly takes a short time to pull the pump out of the well.

Having thus described the invention, what is claimed is:

1. A working barrel structure comprising a fitting provided at itsopposite ends cylinder, said fitting being provided with passagewayswhich communicate with the upper end of the cylinder, the valve memberslidably mounted upon th smaller nipple and adapted to close the upperends of said passageways, the said fitting being provided with otherpassageways located beyond the first mentioned. passageways, and a valvemember located upon the larger nipple and adapted to be disposed in thelower end of tie second mentioned passageways.

2. A working barrel structure comprisin a fitting having nipples at itsopposite ends, the said fitting being provided with an inner set ofpassageways communicating at one end with the interior of one nip- 1e,and having their other ends located yond the exterior side of the othernipple, a valve member slidably mounted upon the last mentioned nippleand adapted to close against the ugper end of the said assa eways, the'sai fitting being provied with other passageways located beyond thefirst mentioned passageways, a Valve member slidably mounted upon thelower nipple and adapted to close against the lower end of the secondmentioned passageways, a cage mounted upon the fitting, and a packingsleeve located. upon the exterior surface of the fitting and below thecage.

In testimony whereof I aifix my signature.
